Question

• Use the equation y 5 ax3 1 bx2 1 cx 1 d. Solve for the variables
a, b, c, and d using a 4 3 4 inverse matrix.

Answer 1

Mimi: Don't take this personally, but you need a bit of practice typing in equations. The one you provided should look like this:
\[y=5ax ^{3}+1bx ^{2}+cx +d.\]
I'm not at all sure that all those signs should be (+) signs. Please verify!
